Description

Technical Field

[0001] The present application relates to the technical field of electrical connection devices, and in particular to a connector device for connecting battery terminals. Background Art

[0002] At present, many cars still use lead-acid batteries as the main power source, especially in traditional fuel vehicles and some early new energy vehicles. The positive and negative terminal materials of lead-acid batteries are usually pure lead or lead alloy. By tightening the fasteners of the joints on the car, the joints are tightly connected to the lead terminals of the battery, thereby achieving a reliable electrical connection. Since lead and its alloys are relatively soft, during the tightening process of the joints, the surface of lead and its alloys will produce a certain amount of plastic deformation to form pits, which makes it difficult for the lead terminals to fall off from the joint components during use, ensuring the stability of the connection.

[0003] As lithium prices continue to fall, lithium batteries are becoming more and more cost-competitive. At present, lithium batteries have been widely used in many fields such as passenger car starting, commercial vehicle parking air conditioning, and auxiliary low-voltage batteries for new energy vehicles, and their market share is increasing rapidly. Compared with traditional lead-acid batteries, lithium batteries have higher energy density, longer service life, and better charging and discharging efficiency. In addition, lithium batteries also have environmental advantages, do not contain heavy metals, and reduce pollution to the environment. Therefore, replacing lead-acid batteries with lithium batteries has become an important trend in the automotive industry.

[0004] Although lithium batteries have many advantages, there are still some technical challenges after replacing lead-acid batteries with lithium batteries. In particular, the positive and negative terminals of lithium batteries are generally made of copper or copper alloy materials, which have better conductivity than lead, but are harder and less likely to deform. Therefore, when the connector components are matched with the copper terminals of the lithium battery, due to the vibration generated by the car during driving, the copper terminals may gradually loosen and eventually fall off from the connector components, thereby affecting the normal use of the car and may even cause dangerous accidents. In order to solve this problem, some vehicles have replaced connectors that can be adapted to connect with copper terminals, but this undoubtedly increases the cost of improvement. Therefore, how to solve the problem of copper terminals falling off from connector components by technical means while using the original connectors has become a problem that must be solved. Finding a solution that can ensure reliable connection and can be achieved with minimal investment will be the current direction of development. Summary of the invention

[0037] The present application is further described in detail below in conjunction with the accompanying drawings.

[0038] Reference Figure 1 and Figure 2As shown, a connector device for connecting battery terminals of the present application includes: a connector component 1 for sleeved on the battery terminal 3, so that the connector component 1 is electrically connected to the battery terminal 3, and the connector component 1 is also connected to the wiring component 6, so that the power-consuming device can be connected to the battery terminal 3 through the wiring component 6 and the connector component 1, so that the electric energy in the battery pack 5 can be used by the power-consuming device. In the existing design, for example: if the battery terminal 3 is a lead terminal or a lead alloy terminal, since the connector component 1 has a fastening function, under the clamping force of the connector component 1, the lead terminal or the lead alloy terminal will be deformed to form a pit, which is equivalent to the connector component 1 being able to be slightly embedded in the battery terminal, which can improve the stability of the electrical connection between the connector component 1 and the battery terminal. When the battery terminals are replaced with copper terminals or copper alloy terminals, although the conductivity is significantly improved, copper terminals and copper alloy terminals are harder and less likely to deform than lead terminals, which reduces the stability of the electrical connection compared to lead terminals or lead alloy terminals. Therefore, the technical point of the present application is that, on the basis of the connector component 1 being sleeved on the battery terminal 3, an anti-loosening component 2 is added, and a structure for installing the anti-loosening component 2 is opened on the battery terminal 3, and the structure for installing the anti-loosening component 2 is the first threaded hole 30, and the anti-loosening component 2 has an installation structure that can cooperate with the first threaded hole 30, that is, an external threaded structure that is compatible with the first threaded hole 30. Since the battery terminal 3 is generally a conical structure, that is, a conical structure that gradually expands toward the battery pack 5, the anti-loosening component 2 can be installed on the outer end of the battery terminal 3 by threaded cooperation. Since the maximum diameter of the anti-loosening component 2 is larger than the diameter of the connector component 1 and is located on the outer end of the battery terminal 3, the connector component 1 can be limited from falling off through the outer end of the battery terminal 3. In the present application, the straight line direction between the battery pack 5 and the outer end of the battery terminal 3 can be defined as a first direction, and the anti-loosening component 2 can also apply a first force pressing downward toward the battery pack 5 on the connector component 1 along the first direction. Since the battery terminal 3 is a conical structure, that is, the closer the radial side of the battery terminal 3 is to the battery pack 5, the larger the size is, so that under the drive of the first force, the connector component 1 can fully contact with the battery terminal 3 to improve the stability of the electrical connection. It can be understood that the anti-loosening component 2, on the basis of preventing the connector component 1 from falling off, also prevents the occurrence of poor electrical contact or even electrical disconnection caused by insufficient contact between the connector component 1 and the battery terminal 3.

[0039] First embodiment

[0040] Reference Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the anti-loosening component 2 includes: a limiting component 21 and a resisting component 22; the limiting component 21 can be installed in the first threaded hole 30 on the battery terminal 3 by threaded fitting, and an installation spacing that can be adjusted by threaded fitting is formed between the limiting component 21 and the joint component 1, and the resisting component 22 is arranged in the installation spacing. During installation, the installation spacing can be adjusted to be smaller than the original support height of the resisting component 22 by threaded fitting between the limiting component 21 and the battery terminal 3, so that the resisting component 22 is supported between the limiting component 21 and the joint component 1 by interference fitting, so that a first force pressing down toward the battery pack 5 in the first direction can be applied to the joint component 1. In the present application, the resisting component 22 has an elastic deformation characteristic, so that the resisting component 22 can continuously apply the first force to the joint component 1, and while preventing the joint component 1 from falling off through the outer end of the battery terminal 3, the contact area of ​​its electrical connection is increased by the cooperation of the conical structure of the battery terminal 3 and the first force.

[0041] Reference Figure 3 As shown, in some embodiments, the limiting component 21 may include: a mounting portion 21a and a limiting portion 21b; the mounting portion 21a is a rod-shaped structure, and an external thread structure compatible with the first threaded hole 30 is provided on the radial side of the mounting portion 21a to constitute the above-mentioned mounting structure, and the limiting portion 21b is arranged at one end of the mounting portion 21a, and the size of the limiting portion 21b is larger than the first threaded hole 30. When the mounting portion 21a and the first threaded hole 30 are fastened by threaded cooperation, the limiting portion 21b can apply pressure on the abutting component 22 along the first direction, so that the abutting component 22 further applies the pressure on the joint component 1 to form a first force. In this embodiment, the limiting component 21 can be a bolt component, its mounting portion 21a can be a screw rod of the bolt component, and its limiting portion 21b can be a screw head of the bolt component, and the external thread structure on the screw rod and the internal thread structure in the first threaded hole 30 can be provided with anti-loosening functional structures, such as: spring washers: cylindrical spring washers placed between the first threaded hole 30 and the bolt, using their elastic deformation to increase friction to prevent the bolt from loosening; threaded holes with nylon rings embedded inside, the nylon rings are in close contact with the bolts after tightening to prevent the bolts from loosening. Stop washers: open washers whose opening part is stuck between the bolt head and the abutting component 22 during installation to prevent it from rotating; or serrated washers with serrated edges to increase friction to prevent the bolts from loosening, etc.

[0042] Reference Figure 4As shown, in some embodiments, the resisting component 22 may include: a force-bearing portion 22a and a force-applying portion 22b; the force-bearing portion 22a can cover the outer end portion of the battery terminal 3 to form a force-bearing table for the limiting portion 21b to press down, and a through hole 22c for the mounting portion 21a to pass through is opened on the force-bearing portion 22a, so that the mounting portion 21a can pass through the through hole 22c and be connected to the first threaded hole 30 in a threaded manner. In this embodiment, the size of the through hole 22c is smaller than the size of the limiting portion 21b, that is, the size of the through hole 22c is smaller than the size of the screw head. The size of the force-applying portion 22b is sized so that after the mounting portion 21a is threadedly engaged with the first threaded hole 30, the limiting portion 21b can abut against the force-bearing portion 22a; and the force-applying portion 22b can be formed on the side of the force-bearing portion 22a close to the connector component 1 or on the outer edge of the force-bearing portion 22a, and the extension direction of the force-applying portion 22b is the first direction, so that the force-applying portion 22b can be supported on the connector component 1 along the radial side of the battery terminal 3, and the first force is applied to the connector component 1 by pressing the limiting portion 21b against the force-bearing portion 22a.

[0043] It should be noted that the elastic deformation characteristics of the abutting component 22 may be derived from the molding structure of the force-applying portion 22b. In the embodiment of the present application, the force-applying portion 22b has a notch 22d arranged along the radial direction of the abutting component 22, so as to reduce the rigidity characteristics of the force-applying portion 22b and make it have sufficient elastic characteristics and toughness. Alternatively, the elastic deformation characteristics may also be derived from the abutting component 22 being made of a material with elastic characteristics.

[0044] Second embodiment

[0045] Reference Figure 2As shown, in some embodiments, when the battery terminal 3 adopts an inverted cone structure, that is, the size of the battery terminal 3 gradually decreases toward the direction of the battery pack 5, the size of the abutting component 22 is still set to be larger than the size of the outer end of the battery terminal 3, and the size of the outer end of the battery terminal 3 is the maximum size on the battery terminal 3, which can further prevent the connector component 1 from falling off through the outer end of the battery terminal 3, but when the connector component 1 is easy to move toward the direction close to the battery pack 5, the battery terminal 3 is an inverted cone structure, so that the electrical connection is poor. Therefore, the difference between this embodiment and the first embodiment is that the anti-loosening component 2 can also include: an elastic element 23; the elastic element 23 can be elastically supported between the side of the connector component 1 away from the abutting component 22 and the battery pack 5, and the elastic force of the elastic element 23 is used as a force to limit the displacement of the connector component 1 on the battery terminal 3 toward the battery pack 5, that is, a second force toward the abutting component 22 is applied to the connector component 1 along the first direction. In the present application, the elastic element 23 may be a pressure spring, which may be sleeved on the battery terminal 3 and be in a compressed state when supported between the connector component 1 and the battery pack 5. In the present application, the battery pack 5 may have a terminal base 4 for stabilizing the battery terminal 3. Therefore, the two elastic ends of the pressure spring may be supported between the connector component 1 and the terminal base 4 to avoid the elastic force of the pressure spring from pressing against the battery pack 5 for a long time and causing adverse effects. After the battery pack 5 and the pressure spring are separated by the terminal base 4, the contact area between the terminal base 4 and the battery pack 5 is larger than the release area of ​​the pressure spring directly contacting the battery pack 5, thereby weakening the pressure applied by the pressure spring on the battery pack 5 and avoiding adverse effects on the battery pack 5. When in use, the force of the pressure spring's stored force rebound can support the connector component 1 in a position in full contact with the battery terminal 3, that is, the rebound force of the pressure spring is greater than the weight of the connector component 1 itself.

[0046] Reference Figure 5 and Figure 6 As shown, in some embodiments, the connector component 1 may include: a clamp member 11 and an adjustment component 12; the clamp member 11 is used to be sleeved on the battery terminal 3, and the clamp member 11 is configured as an electrical conductor structure, that is, it is made of a conductive structure, such as: metal copper, so that the clamp member 11 can be electrically connected to the battery terminal 3; the adjustment component 12 is configured on the clamp member 11 to be able to adjust the tightness of the clamp member 11, so that the clamp member 11 can change the clamping force on the battery terminal 3, so that the clamp member 11 can be stably electrically connected or removed on the battery terminal 3 through the adjustment component 12.

[0047] Reference Figure 5As shown, in one embodiment, the clamping member 11 has a clamping portion 11a and a connecting portion 11c; the clamping portion 11a is an open-loop structure, so that the battery terminal 3 can enter the clamping portion 11a through the opening on the open-loop structure, and the ends of the clamping portion 11a located on both sides of the opening extend to form two adjusting portions 11b, and mounting holes 11d for configuring the adjusting assembly 12 are provided on the two adjusting portions 11b, so that the tightness of the clamping portion 11a can be changed by tightening the adjusting portion 11b through the adjusting assembly 12; the connecting portion 11c is formed on the ring body of the clamping portion 11a, and can be located on the side of the clamping portion 11a away from the adjusting portion 11b, and an electrical connection port 11e capable of electrical connection is provided on the connecting portion 11c. In this embodiment, the electrical connection port 11e is a closed-loop structure, so that the wiring component 6 can be fixed to the connecting portion 11c through the cooperation of a fastener with the electrical connection port 11e to achieve electrical connection.

[0048] Reference Figure 6 As shown, in some embodiments, the adjustment component 12 may include: a first fastener 121 and a second fastener 122; the first fastener 121 may have a limit head 121a and a rod body 121b, the size of the limit head 121a is larger than the size of the two mounting holes 11d so that it can abut on the adjustment portion 11b, and the rod body 121b can be inserted into the mounting hole 11d, and an external thread structure is provided on the rod body 121b; the second fastener 122 is provided with a second threaded hole with an internal thread structure, which is configured on the rod body 121b by means of anti-loosening thread matching, and the size of the second fastener 122 is also larger than the size of the mounting hole 11d, So that the second fastener 122 can abut against the adjusting portion 11b, when the first fastener 121 and the second fastener 122 tighten and limit the two adjusting portions 11b, the two adjusting portions 11b are supported between the limiting head 121a and the second fastener 122 through the rod body 121b. In this embodiment, the first fastener 121 can be a bolt, and the second fastener 122 can be a nut, and the bolt and the nut adopt one of the anti-loosening thread structures in the above embodiments, or other types of anti-loosening thread structures can also be adopted, so as to prevent the bolt and nut thread structures from loosening to some extent or in some cases, which is not limited here. Therefore, the looseness of the clamping portion 11a can be changed through the adjusting portion 11b by screwing in or out the nut.

[0049] In some embodiments, the adjustment component 12 may also include: a first fastener 121 and two second fasteners 122; the first fastener 121 is a rod-shaped structure that can be inserted into the mounting hole 11d, and an external thread structure is provided on the radial side of the first fastener 121; and the two second fasteners 122 are respectively provided with second threaded holes with internal thread structures, so as to be configured on the first fastener 121 by means of anti-loosening thread matching, and the sizes of the two second fasteners 122 are both larger than the sizes of the mounting hole 11d, and are used to abut against the adjustment part 11b. When the first fastener 121 and the two second fasteners 122 fasten and limit the two adjustment parts 11b, the two adjustment parts 11b are located between the two second fasteners 122 through the support of the first fastener 121. In this embodiment, the first fastener 121 can be a screw with an external thread structure, and the second fastener 122 can be a nut that can be screwed into the screw by thread matching, and the screw and the nut also adopt an anti-loosening thread structure, which adopts the same anti-loosening thread structure as the above embodiment, so it will not be repeated. Therefore, by screwing in or out the nut on the screw, the tightness of the clamping part 11a can be changed through the adjustment part 11b.
